The standard enforces strict structural design principles to eliminate flashover risks and accidental physical contact. It specifies minimum air clearances based on the system's rated impulse withstand voltage. For indoor sub-stations, the baseline clearance demands at least the danger zone dimension plus 200 mm (minimum 500 mm), whereas outdoor setups mandate a threshold of the danger zone plus 300 mm (minimum 600 mm). 2.

The rules are intended to protect persons, livestock, and property from hazards and damage arising from the proper use of such electrical installations, while ensuring their safe functioning. iec 6193612021 link

The new version places a heavier emphasis on a "risk-based approach." Instead of just following rigid tables, engineers are encouraged to evaluate specific site conditions to determine safety distances and protective measures. 2. Updated Clearances The standard enforces strict structural design principles to
